In the given question Laura has $30 to spend on food for the week.
According to the question we have to set the inequality between total amount and amount spent on food.
Amount spend by Laura on food for the week = $30
Let the amount spent by Laura on food be x
So she has to spend up to $30
So inequality will be 
So option b is the answer
Answer:
a. 48
b. You need 6 packs of cups and 8 packs of plates
c. 72 is another one she would need 9 packs of cups and 12 packs of plates to get this one
Answer:
0.50
Step-by-step explanation:
P(A|B)=P(A and B)/P(B) is the formula to find a conditional probability when A and B are not independent.
A and B are independent. This means B has no effect of A. This means P(A|B)=P(A).
P(A|B)=P(A) since A and B are independent
P(A|B)=0.50
You can conclude that AE = DE because the triangles are about equal
